I have narrowed the list a little bit further.

I would like to explain one thing here. You technically would only need to have a DPST relay. That would mean that you would have two switches being switched with signal. Each of those switches would have only one contact to switch to.
You would also have to choose if you want those internal switches to be normally on or normally closed. This is the state it is in when there is not any signal present. Your request implies that you would want it to be normally closed. This way when your temp sensor goes down, so does your load.
with that being said, a DPDT type of relay allows you to choose as each switch as terminals for the activated state as well as the deactivated state. These are the options in the link above.
